ELECTRICAL SPECIFICATIONS
Accuracy is given as ± (% of r counts of least
significant digit) at 23 °C ± 2 °C (≤ 80% R.H.)
AC Function
• AC A specifications are AC coupled, true RMS.
• For non-sinusoidal waveforms, Additional Accuracy by
Crest Factor (C.F.):
Add 1.0% for C.F. 1.0 to 2.0
Add 2.5% for C.F. 2.0 to 2.5
Add 4.0% for C.F. 2.5 to 3.0
• Max. Crest Factor of Input Signal:
3.0 @ 3000 counts
2.0 @ 4500 counts
1.5 @ 6000 counts
• Frequency Response is specified for sine waveform.
• When operating under magnetic field add error E11.
• When measuring leakage current of multiple conductors,
add error E12 for influence of load current.
• For Position Error see error E1.
